I have a sweet idea, branching skills, where if you learned a certain ability in one skill and a certain ability in another skill, it would produce a totally different skill. like if you learned up to IllusorySelf in Glamours and and Minorsecond in Music you should be able to create a skill in which your illusion attacks the enemy maybe called, Illusionstrike or something like that, while you're attacking the enemy at the same time.

These already exist but are very rare, as they would be a pain to implement and balance. The most notable one that comes to mind would be Astroglide in Astrology, a skill which allows an astrologer to jump directly to the Astral plane. This requires a certain skill rank in Astrology as well as the Planar skill AstroGate. The Enchantment tradeskill is also a good example of these. In order to enchant the majority of the effects, you must know the corresponding HighMagic/Elementalism/Cosmic skill, as the majority of enchantments are direct replications of the existing skills.

If you want the idea to be potentially taken more seriously, why don't you come up with a few good examples, including exact effect (though not exact down to the numbers, a relative amount is fine), relative cost, and why you think it's a good addition to whatever skillset you put it in?

ok, ill have to do my homework for this one haha, ill reply back with a few examples.
